Bootup time gets affect by... - Samsung Galaxy S7 Edge Questions and Answers

Does the boopup time (lets say rebooting your phone) gets affected by the custom rom youre using or the kernel youre using?

Unresponsive spots on screen, have to reboot :(

After a few hours of using the phone, certain parts of the screen become un responsive and i have to reboot to fix it. Im using Cyanogenmod #104 right now (its happened since, well from the beginning)
Any fixes to this? Im using the latest Telus radio too (not that it mattered)
try different rom and see what happens, i doubt it's rom issue
Does it fix itself if you let it sit for a bit? I would say to reflash the ROM or try something else like ARHD which is the most stable Sense ROM we have at the moment I believe.
I doubt its hardware because as you say it is only temporary until reboot.
Make sure you do a full wipe and flash a ROM. Then we will take it from there.

[Q] is it good to not check restart...?

When im using odin, is it good for the phone to not check restart, and pull the battery instead then restart? This really is in refrence to rooting the EH11 system. It takes a few times to get odin to actually boot strait into CWM when i flash it over but if the phone reboots then CWM gets overridden. This is the only surefire way ive seen thus far to get it to work every time and before i recommend it to anyone, id like to know if there is a theoretical room for damage to the phone or filesystem by pulling the battery after odin completes.

Every custom ROM restart issues, eventually bootloops

over the last few days I've flashed a number of ROMs, mostly the Google Edition 4.2.2 and 4.3 ones and every single one of them eventually fails to boot hanging on the Samsung bootloader screen. and i say eventually because the first boot is almost always flawless, but then each time i reboot or power down, its almost guaranteed to loop.
I've tried so many different combinations that there's really not a single path I've taken every time, but the general steps are:
-root original firmware using motochopper
-install TWRP via GooManager
-reboot recovery and wipe everything, typically I do Advanced and select everything, then format Data
-then flash through ADB sideload, I do this since I wipe everything before flashing and I don't have an external SD card
-immediately after flashing ROM, I flash loki-doki also through ADB sideload. some of the ROMs I tried said they were lokied, but I still got the ATT invalid ROM message, so I reflashed with loki and it worked.
-then reboot system and the first time it comes up and works fine on every ROM I've tried
But if I power down or restart, on a very rare occasion it'll come up, but almost every time it hangs on bootloader screen. I also noticed once it's stuck on bootloader, power button becomes unresponsive, sometimes holding it powers down device, sometimes does nothing (have to press and hold twice)
If I flash back to stock using Odin, it works, boots, reboots, powers down just fine.
I've also tried flashing with a ROM and then immediately after with the stock ATT kernel, also booted up fine, but looped on restart.
Could this be hardware issue?
I'm about to give up on this and go back to stock for good, which would be really disappointing, can anyone help?
Flash a KT kernel and see what happens, I suppose you know which one correct?

I assume KT means http://forum.xda-developers.com/showthread.php?t=2292341 ?
I've tried that too with jamal2367's 4.2.2 GE ROM (http://forum.xda-developers.com/showthread.php?t=2341794). It refused to boot all together.
First time I flashed with AOSP version since I thought that was an AOSP ROM, then reading more comments in the other thread it said I needed the TW version for GE ROMs, so I tried that too. Either way, neither of them booted at all, even the first time, so I gave up on KT and only used either ROMs' included kernels or ATT stock.
It is not a hardware issue, I am guessing that you have a US ATT G4 correct? I would odin back to stock, and restart the process again, this is assuming you tried the correct TW kernels. Because I know this error and all it requires is a simple flash of the correct kernel.

OK I'll try one more time from scratch, can you verify I'm using the right stuff though for US ATT Galaxy S4:
ROM: http://forum.xda-developers.com/showthread.php?t=2341794
Kernel: http://forum.xda-developers.com/showthread.php?t=2292341 (TW one, specifically http://goo.gl/SiDjB)
And any idea why the ROM's kernel wouldnt work after being lokied?

You know, I don't even look at anything that says loki anymore, I flash the rom I want and use MY carriers kernel, bootloops and hangs are just not there, I do not see these issues everyone has, because, I have this procedure everytime. So...
Btw, your good on your files you want to flash, but, if this does not work ie, GE and that kernel, try a TW rom with the kernel, bet it boots properly. I do not give a rats
a$$ about goole roms. They are not worth it. Btw, I use this procedure on TW and aosp roms, no issues. Just because it says it loki'ed, flash the kernel you know works, loki just confuses people.
The Ax says again an again..My opinion only!
Good luck sir.
BTW, I ran that rom with the kernel you chose, it should work just fine. Remember, flash the TW version.
Thanks Ax for your help here, your welcome.

[Q] Rebooting after flashing Rom

Hi,
I have been trying to flash few roms. I constantly do though. Last rom I was on, I found that the battery drained very quickly and it keeps changing its stats in a random way.
I decided to flash new roms, and since, I flash the rom, and then the phone turns off by itself. I tried few different kernels "of course the right ones", and some seem to help for few more minutes, but that is not the case.
I tried to flash the latest version of "FOXHOUND ROM' for the i9505, and it would show the boot animation and then turns off instead of starting the phone. Tried to wipe cache and all the stuff, and still the problem persisted. Could it be a bad battery all of the sudden?

Go back to stock first, and check if that has the same problems...

For some reason I have tried this a lot on my old phone... Some kernels worked for mine and others not... While it should..
Flash stock and see... Keep stock kernel and flash rom, if no problems then try new kernel... If problem returns then flash stock kernel again

Thanks for the tip. I tried that as well, but Unfortunately, the same problem. I don't have a problem what so ever when I am using the phone while it is charging or plugged in, but as soon as I take it out, and even if it is full, it shuts off, tries to turn back on and it wouldn't, it keeps rebooting, once i plug the charger in it, it would stay on.
That tells me either:
The Battery is bad!
Or
There might be a circuit problem with the phone sucking power out of the battery!

Omega ROM boots very slow - GT-I9500

Hello, I'm having an issue with my phone where every time I reboot, it takes a very long time to boot up. It was fast the first time I flashed it but I had to re-flash it due to other issues. Now the boot is slower than my stock rom. And to add salt to the wound, it'll frequently say something along the lines like "Optimizing apps 1/4" or "Android is upgrading".

According to the thread of the rom, that version has some bugs. I would suggest moving to a rom that is still being mainted.
